Measuring the buoyancy of vacuum / Weighing air

[@EmersumBiggins]

Excellent demonstration 👍

👌👌👌

hehe one of the Aetherboys was telling me that vacuum didn't have buoyancy like hydrogen does.

Excellent demonstration. I like the backwards-and-forwards nature of your demonstration, in addition to "addressing the rubber hose" question. Perfectly done. I will say that your initial reading was 0.04 lbs, but the online calculator says 0.05 lbs, which means you've proven the Earth to be Flat. 😛

Exactly! I was basically measuring the column weight of the air within the pot!

Off topic Jesse. Your Lewin Clock (perfect name) has just been covered Trevor Kearney.

Thanks :D I kind of skipped around in his new video, I see he's going on about ohms law. The other day I checked the voltage on my car's battery. It was 12.3 volts. Assuming an internal resistance of 0.01 ohms, we can use ohms law to calculate that the battery was delivering 1230 amps to my volt meter. Which is funny because my volt meter has a 10megohm/volt input impedance, so I would like to know how many volts it takes to push 1230 amps through my volt meter! (Read parody here.)

Also demonstrates air has mass

[@fromjesse]

Indeed!

[@ReinoGoo]

And that mass has weight. So there is no need for a flat earth, or a sealed container.

now you gotta do this again but by adding hydrogen or helium to higher than atmospherical pressure, showing that it'll get heavier, to address further misconceptions of our fellow flerfs

[@fromjesse]

Actually, it's well known that helium tank pressurized to 2000 PSI is heavier, so that's been done! (And due to the Obviously my vacuum chamber can't hold pressure because it is the outside air pressure that holds the lid on! However, it would be interesting to pump a vacuum, show the reduced weight, and then let back in helium instead of air, and show that helium actually does have more weight than vacuum. Helium is kind of expensive unless you get a helium balloon kit for like $33USD which is still kind of a lot for one experiment.

Whalen’s is you out a balloon in the vac
